David Gregory, host of NBC's "Meet the Press," noted on the show Sunday that pro-gun rights senators in the new Congress had declined to go on the show to discuss guns two days after the shooting at Sandy Hook Elementary School in Newtown, Conn. 

"We reached out to all 31 pro-gun rights Senators in the new Congress to invite them on the program to share their views on this subject this morning," Gregory said. "We had no takers."
